Execute gofmt on file save in IntelliJ

If you are using Gogland, you have an option On Save under Preferences

Gogland EAP 16 deprecated the On Save actions and replaced them with the File Watchers plugin.

If you have previously configured On Save actions, the IDE will prompt you to install the plugin and configure everything automatically. If you want to set it up from scratch yourself, check if you have File Watchers plugin and if not install it.

Enable gofmt:

1. Go to Settings | Tools | File Watchers.
2. Click the + button and select go fmt.
3. The default values are good.
4. In Advance Options select:
   • Auto-save edited files to trigger the watcher
   • Trigger the watcher on external changes
5. Click ok!

You can do the same for goimports and gometalinter.

Of course you can.

1. install File Watchers plugin
2. open "Preferences->Tools->File Watchers" & Add a new watcher
3. set File Type: Go, Program: the abosolute path of gofmt, Arguments: -w $FilePath$
4. click OK
